DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In order to make the purpose, technical solutions, and effects of the present disclosure clearer and more definite, the following further describes the present disclosure in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the disclosure, and are not used to limit the disclosure.

FIG. 1 is a schematic structural diagram of a pixel layout according to an embodiment of the present disclosure. Referring to FIG. 1 , an embodiment of the present disclosure provides the pixel layout. The pixel layout includes a plurality of pixel repeating groups, wherein each of the pixel repeating groups includes an array substrate and a first pixel 1, a second pixel 2, a first through-hole 61, and a second through-hole 62 defined on the array substrate. The first pixel 1 is adjacent to the second pixel 2, and the first through-hole 61 and the second through-hole 62 are defined between the first pixel 1 and the second pixel 2; a first end of the first through-hole 61 is electrically connected to a pixel electrode 101 of the first pixel, and a first end of the second through-hole 62 is electrically connected to a pixel electrode 102 of the second pixel; and when the pixel electrode 101 of the first pixel 1 or the pixel electrode 102 of the second pixel 2 has a voltage loss, a second end of the first through-hole 61 is electrically connected to a second end of the second through-hole 62.

Specifically, in order not to affect overall aperture ratio of the first pixel 1 and the second pixel 2 and electrical connections among wirings in the pixel layout, the first through-hole 61 and the second through-hole 62 are positioned between the first pixel 1 and the second pixel 2. Wherein, the first end of the first through-hole 61 is electrically connected to the pixel electrode 101 of the first pixel, the first end of the second through-hole 62 is electrically connected to the pixel electrode 102 of the second pixel, and another end of the first through-hole 61 and another end of the second through-hole 62 are in a floating state, so that when the pixel electrode 101 of the first pixel has the voltage loss and causes the first pixel 1 to have a dark spot or when the pixel electrode 102 of the second pixel has the voltage loss and causes the second pixel 2 to have the dark spot, the second end of the first through-hole 61 and the second end of the second through-hole 62 can be electrically connected, thereby allowing one pixel having the dark spot to display normally with help of another pixel adjacent thereto.

The pixel layout provided by this embodiment of the present disclosure positioned the first through-hole 61 and the second through-hole 62 between the first pixel 1 and the second pixel 2 adjacent to each other, the first through-hole 61 is electrically connected to the pixel electrode 101 of the first pixel, and the second through-hole 62 is electrically connected to the pixel electrode 102 of the second pixel. When the pixel electrode 101 of the first pixel or the pixel electrode 102 of the second pixel has the voltage loss and that causes the first pixel 1 or the second pixel 2 to have a dark spot defect, the second end of the first through-hole 61 and the second end of the second through-hole 62 are electrically connected, thereby connecting the pixel electrode of the pixel having the dark spot defect to the pixel electrode of the other pixel to allow the pixel having the dark spot defect to display normally with help of the other pixel, thereby repairing the pixel having the dark spot defect. In addition, since the first through-hole 61 and the second through-hole 62 are positioned between the first pixel 1 and the second pixel 2, overall aperture ratio of the pixels is not affected.

It can be understood that FIG. 1 uses two pixels adjacent to each other in a same column of two stages of gate driver on array (GOA) units as one pixel repeating group, and actually, two pixels adjacent to each other of a same staged GOA unit can also be used as one pixel repeating group.

It should be noted that specifically, the second end of the first through-hole 61 being electrically connected to the second end of the second through-hole 62 is achieved by using laser to weld the second end of the first through-hole 61 and the second end of the second through-hole 62 together.

Referring to FIG. 1 , the array substrate includes a spacing area 3 defined between the first pixel 1 and the second pixel 2, and the first through-hole 61 and the second through-hole 62 are positioned in the spacing area 3, thereby preventing the overall aperture ratio of the pixel layout from being affected.

It should be noted that the first pixel 1 and the second pixel 2 are arranged symmetrical to each other with respect to the spacing area 3.

Referring to FIG. 1 , each of the pixel repeating groups further includes a common electrode line disposed on the array substrate, and the common electrode line includes a shared electrode line 4, a first extending part 41, and a second extending part 42. The shared electrode line 4 is positioned in the spacing area 3, the first extending part 41 is positioned in the first pixel 1 and on one side of the first pixel 1 facing away from the shared electrode line 4, and the second extending part 42 is positioned in the second pixel 2 and on one side of the second pixel 2 facing away from the shared electrode line 4. The first extending part 41 and the second extending part 42 are electrically connected to the shared electrode line 4 respectively. It should be noted that the shared electrode line 4, the first extending part 41, and the second extending part 42 together form the common electrode line. The first extending part 41 and the pixel electrode 101 of the first pixel form a first storage capacitor to keep a charged voltage of the first pixel 1 until a moment of a next updated image, and the second extending part 42 and the pixel electrode 102 of the second pixel form a second storage capacitor to keep a charged voltage of the second pixel 2 until a moment of a next updated image.

In addition, in order to facilitate the electrical connections between the first through-hole 61 and the first pixel 1 and between the second through-hole 62 and the second pixel 2, and to prevent wirings between the second end of the first through-hole 61 and the pixel electrode 101 of the first pixel and between the second end of the second through-hole 62 and the pixel electrode 102 of the second pixel from being too long, a projection of the shared electrode line 4 on the array substrate coincides with projections of the first through-hole 61 and the second through-hole 62 on the array substrate.
